Biological Treatment

Biological treatment relies on microorganisms breaking down dissolved organic matter. COD and BOD removal along with nitrogen and phosphorus removal take place at this stage.

Systems we apply

• Conventional activated sludge (extended aeration)
• MBR — membrane bioreactor
• MBBR — moving bed biofilm reactor
• Anaerobic pre-treatment for high COD loads
• Nitrification / denitrification stages
